Many people say this is the easiest method of suspension.
It's comparatively easier than other methods, and I myself do it a lot, but there are still some points you need to pay attention to, so I'll explain those as well.
First, ask your partner whether they'd rather have their left or right side be on the bottom. Different people prefer different directions, so you should match your method to their tastes.
The order is the same as horizontal suspension: chest, legs, waist.
Use the photos to help you figure out where to pass the suspension rope through.
If you pass it through the rope around the arms, it may cause friction, so be careful.
If you fasten it too high, you will be unable to raise the legs to the same height, so try to keep the chest rope slightly lower than the rest.
Raising the legs a bit higher than the chest will make the finished product look nicer.
(Make sure the waist rope is tight, or else it may slip off the pelvis.)
(Here, the waist is too low)
(The waist is too high)
You can do this with your hands, or apply rope to the back to curve it.
In this example, I applied rope to the knee of the bottom leg, but there are other methods which involve suspending from the ankle, or folding the leg before suspending.
Do not just leave the rope on the floor after you unravel it. (You could step on it or slip on it and cause an accident.)
(Leaving rope on the floor around your feet is dangerous)
